Ricky Ricotta's Mighty Robot vs. the Mecha-Monkeys from Mars (Ricky Ricotta's Mighty Robot #4) (Library Edition): Volume 4 Library binding - 2014

When Dav Pilkey was a kid, he was diagnosed with ADHD and dyslexia. Dav was so disruptive in class that his teachers made him sit out in the hallway every day. Luckily, Dav loved to draw and make up stories. He spent his time in the hallway creating his own original comic books -- the very first adventures of Dog Man and Captain Underpants.

In college, Dav met a teacher who encouraged him to write and illustrate for kids. He took her advice and created his first book, World War Won, which won a national competition in 1986. Dav made many other books before being awarded the California Young Reader Medal for Dog Breath (1994) and the Caldecott Honor for The Paperboy (1996).

In 2002, Dav published his first full-length graphic novel for kids, called The Adventures of Super Diaper Baby. It was both a USA Today and New York Times bestseller. Since then, he has published more than a dozen full-length graphic novels for kids, including the bestselling Dog Man and Cat Kid Comic Club series.

Dav's stories are semi-autobiographical and explore universal themes that celebrate friendship, empathy, and the triumph of the good-hearted.

When he is not making books for kids, Dav loves to kayak with his wife in the Pacific Northwest.
